It looks like the final naturally aspirated BMW (at least for the US) will indeed be an E92/E93 M3 or 328i. I sort of hope they make it an M3, even though it seems more likely the 3 series will be in production a little longer. But to me it would be fitting to give this honor to the M3.

I think there will be two other NA engine from 2014: M3 F32 with S66 and Z10 wiht S86. If not DIE.

Not this again.

Come on, Levi. "Think" and "pray" are two different things entirely. Every indication points to BMW transitioning to a complete FI lineup. What makes you think they'll spend millions of dollars developing two entirely new low-volume high-performance NA engines? Everything we've been told and have seen in the last 5 years have pointed to BMW completely abandoning NA technology.

It's my (and others) working name for the next M3 engine. No details are known officially, but BMW higher ups have said it will be a turbo six of some kind. Current prevailing belief is a 3L multi-turbo engine with 450hp+.

There seems to be a small but vocal European contingent that refuse to accept reality.

It costs more to build a high reving turbo engine like the McLaren MP4-12C's V8, than to add direct injection to the S65 and S85 that were built from zero for only one generation and two cars, E9X and E6X. Why not continue and profit from it? You could even make a 90° V12 from it.

Never though BMW would be the first among Mercedes and Audi to not offer even one single NA engine. Mercedes will still have the SLK AMG (NA 5.5l V8) and the SLS AMG (NA 6.3l V8) and Audi will still have the R8 (NA 4.2l V8 and NA 5.2l V10), the RS5 and maybe even the next RS4 (NA 4.2l V8) and the A8 W12 (NA 6.2l W12).

Regarding the NA engines that you listed from MB and Audi, those are all legacy engines that are either on their way out (6.3L V8 from MB, 4.2L V8 from Audi) or are NA versions of existing FI engines (5.5L V8 from MB, 6.2L W12 from Audi/VW).

Don't get me wrong, I'll be the first person in line to buy the F32 M3 if it has an NA engine. I just think that's a pipe dream at this point.

By the way, when did you move to Italy? Weren't you living in France not too long ago?

I like turbocharging and BMW does it just about as well as anybody, but theres something about a naturally aspirated engine. To keep up with the competitions horsepower numbers and limit fuel usage it's basically a forced decision
